Member Function Documentation

◆ AltIsPressed()

virtual bool IInput::AltIsPressed ( ) const

pure virtual

Implemented in CInput.

◆ Clear()

virtual void IInput::Clear ( )

pure virtual

Clears the events and KeyPress state for this frame. Must be called at the end of each frame.

Implemented in CInput.

◆ ClearTouchDeltas()

virtual void IInput::ClearTouchDeltas ( )

pure virtual

Must be called after the touch finger states have been used during the client update to ensure that touch deltas are only accumulated until the next update. If the touch states are only used during rendering, i.e. for user interfaces, then this is called automatically by calling Clear.

Implemented in CInput.

◆ ConsumeEvents()

virtual void IInput::ConsumeEvents ( std::function< void(const CEvent &Event)> Consumer ) const

pure virtual

Implemented in CInput.

◆ CursorRelative()

ECursorType IInput::CursorRelative	(	float *	pX,
		float *	pY )

inline

◆ EnsureScreenKeyboardShown()

virtual void IInput::EnsureScreenKeyboardShown ( )

pure virtual

Implemented in CInput.

◆ FindKeyByName()

virtual int IInput::FindKeyByName ( const char * pKeyName ) const

pure virtual

Implemented in CInput.

◆ GetActiveJoystick()

virtual IJoystick * IInput::GetActiveJoystick ( )

pure virtual

Implemented in CInput.

◆ GetCandidate()

virtual const char * IInput::GetCandidate ( int Index ) const

pure virtual

Implemented in CInput.

◆ GetCandidateCount()

virtual int IInput::GetCandidateCount ( ) const

pure virtual

Implemented in CInput.

◆ GetCandidateSelectedIndex()

virtual int IInput::GetCandidateSelectedIndex ( ) const

pure virtual

Implemented in CInput.

◆ GetClipboardText()

virtual std::string IInput::GetClipboardText ( )

pure virtual

Implemented in CInput.

◆ GetComposition()

virtual const char * IInput::GetComposition ( ) const

pure virtual

Implemented in CInput.

◆ GetCompositionCursor()

virtual int IInput::GetCompositionCursor ( ) const

pure virtual

Implemented in CInput.

◆ GetCompositionLength()

virtual int IInput::GetCompositionLength ( ) const

pure virtual

Implemented in CInput.

◆ GetDropFile()

virtual bool IInput::GetDropFile	(	char *	aBuf,
		int	Len )

pure virtual

Implemented in CInput.

◆ GetJoystick()

virtual IJoystick * IInput::GetJoystick ( size_t Index )

pure virtual

Implemented in CInput.

◆ GetUpdateTime()

virtual float IInput::GetUpdateTime ( ) const

pure virtual

Returns: Rolling average of the time in seconds between calls of the Update function.

Implemented in CInput.

◆ HasComposition()

virtual bool IInput::HasComposition ( ) const

pure virtual

Implemented in CInput.

◆ InterfaceName()

const char * IInput::InterfaceName ( )

inlinestatic

◆ KeyIsPressed()

virtual bool IInput::KeyIsPressed ( int Key ) const

pure virtual

Returns whether the given key is currently pressed down. This directly represents the state of pressed keys based on all handled input events.

This function should be used to trigger behavior continuously while a specific key is held down, e.g. for showing a list of all keys that are currently being pressed.

Parameters

Key	The key code (see keys.h).

Returns: true if key is currently pressed down, false otherwise.

Implemented in CInput.

◆ KeyName()

virtual const char * IInput::KeyName ( int Key ) const

pure virtual

Implemented in CInput.

◆ KeyPress()

virtual bool IInput::KeyPress ( int Key ) const

pure virtual

Returns whether the given key was pressed down during input updates for current frame. This state is cleared at the end of each frame by calling the Clear function.

This function should be used to trigger behavior only once per key press event per frame, e.g. for menu hotkeys that should activate behavior once per key press.

Parameters

Key	The key code (see keys.h).

Returns: true if key was pressed down during input updates for the current frame, false otherwise.

Implemented in CInput.

◆ ModifierIsPressed()

virtual bool IInput::ModifierIsPressed ( ) const

pure virtual

Implemented in CInput.

◆ MouseModeAbsolute()

virtual void IInput::MouseModeAbsolute ( )

pure virtual

Implemented in CInput.

◆ MouseModeRelative()

virtual void IInput::MouseModeRelative ( )

pure virtual

Implemented in CInput.

◆ MouseRelative()

virtual bool IInput::MouseRelative	(	float *	pX,
		float *	pY )

pure virtual

Implemented in CInput.

◆ NativeMousePos()

virtual vec2 IInput::NativeMousePos ( ) const

pure virtual

Implemented in CInput.

◆ NativeMousePressed()

virtual bool IInput::NativeMousePressed ( int Index ) const

pure virtual

Implemented in CInput.

◆ NumJoysticks()

virtual size_t IInput::NumJoysticks ( ) const

pure virtual

Implemented in CInput.

◆ SetActiveJoystick()

virtual void IInput::SetActiveJoystick ( size_t Index )

pure virtual

Implemented in CInput.

◆ SetClipboardText()

virtual void IInput::SetClipboardText ( const char * pText )

pure virtual

Implemented in CInput.

◆ SetCompositionWindowPosition()

virtual void IInput::SetCompositionWindowPosition	(	float	X,
		float	Y,
		float	H )

pure virtual

Implemented in CInput.

◆ ShiftIsPressed()

virtual bool IInput::ShiftIsPressed ( ) const

pure virtual

Implemented in CInput.

◆ StartTextInput()

virtual void IInput::StartTextInput ( )

pure virtual

Implemented in CInput.

◆ StopTextInput()

virtual void IInput::StopTextInput ( )

pure virtual

Implemented in CInput.

◆ TouchFingerStates()

virtual const std::vector< CTouchFingerState > & IInput::TouchFingerStates ( ) const

pure virtual

Returns a vector of the states of all touch fingers currently being pressed down on touch devices. Note that this only contains fingers which are pressed down, i.e. released fingers are never stored. The order of the fingers in this vector is based on the order in which the fingers where pressed.

Returns: vector of all touch finger states
